Tips for Training for a Half Marathon on a Treadmill

With the goal of getting you marathon-ready, we have come up with a workout schedule that will optimize your body’s performance and prepare you for the big race.

  1. Create A Conducive Half Marathon Environment

Most marathons take place in warmer weather. If, for instance, you train during winter, the temperatures are going to be drastically different. Training in winter means icy roads, fewer daylight hours and sub-zero temperatures. During winter it’s obviously warmer inside than outside. With your treadmill being indoors, there’s no reason to miss a run due to bad weather. Since you’re at home, you can tweak your surroundings to mimic the race-like conditions better and combat each of these barriers. By making the temperature comparable to what it will be on the race day, you can try out different race day outfits.

Most people develop boredom during races, and some don’t even reach the finish line. With a treadmill, you can come up with strategies to deal with the mental challenges ahead of time. Consider switching your entertainment. Load up audiobook, podcasts, and add some bumping music playlist to cycle through. If you are a TV person, pick your favorite shows on Netflix. Fitness programs like iFit Coach will also help you shake up your training.

  1. Practice With An Incline

Road conditions are never completely flat. The monotony of steady pace running can be boring. Many folks make a habit of training at a 0 percent incline. If you constantly train on a flat surface, you will find it challenging to meet your fitness goals. You will stress the same muscles repeatedly. One advantage of training for a half marathon on a treadmill is versatility. A treadmill closely mimics running outside but provides more cushioning that is easier on joints compared to outdoor terrain.

Treadmills allow you to control the speed as well as the incline every few minutes according to your needs. An incline creates a greater energy demand. A treadmill can work your muscles in a pattern that better simulates running outdoors. The additional strength will improve your speed. Even if your neighborhood is pretty flat, with a treadmill you can add inclines and train for a race that’s going to feature hills. Some treadmills have decline settings to help you prepare to go downhill.

  1. Work On Increasing Your Pace

If you want to win a half marathon, you have to consider your pace before each run. Training for speed outside on a variable terrain requires more effort and memory, a luxury you don’t have. A treadmill provides a controlled environment that lets you run at a pre-chosen pace. Unlike running on outdoor surfaces, you don’t move; the belt does. Your job is to reposition your legs repeatedly. Treadmills feature programming that will increase the intensity of your treadmill runs. This gives you an opportunity to focus on and perfect your pace.

To train on a treadmill, you don’t have to be a crazy running legend. If you are a beginner, you can use a treadmill to gauge how different paces feel and pick a pace that’s right for you. A treadmill will train you to hit time-specific mile repeats and this way you learn how to control your speed more. Making your tempo consistent will come in handy come race day.

  1. Learn How To Prevent Injuries

No one wants to pick up an injury, and the good news is that a treadmill can help you prevent injuries. Incorporate preventative measures like warming up, stretching, icing your feet and cooling down to mitigate the risk. Be careful not to pick an injury while training as this means that you won’t be able to run the half marathon you’ve been training for.

  1. Develop A Custom Plan For You

Runners are not equal. What works for your gym buddy may not work for you. There are several treadmill workouts online, but not all of them have the specificity of your race in mind. Having a training plan will help you reach the required fitness levels. When creating a training plan, you have to take factors like your weight into consideration. Also, consider the marathon area.

Most training plans have one long run and several 3-6 mile maintenance runs each week. Tempo runs help to boost your cardio capabilities and overall fitness. Interval training helps to increase your speed so you can achieve a certain finish time. On some days, practice with a slight incline if your race is in a hilly area. If you stick to your training plan, it will work and you’ll be able to run your half marathon.


Getting ready for a half marathon may be an exciting challenge, but you need to know how and when to use a treadmill to your advantage. It is important to mention that a treadmill isn’t a perfect substitute for training outdoors. Try to shift some of your runs to the outdoors to get a fairly realistic preparation and maximize your race-day potential. Alternating treadmill training with outdoor runs will help you work on your outdoor pace and wind resistance, adapt to the climate and gain road conditioning. This will help you fully prepare for the race.
